As you know, the Canon 7D is now capable of shooting raw video thanks to Magic Lantern.
I've downloaded Pelican's nightly build and install it on my Canon 7D. I did some quick tests in my garden with silent pics burst. For now, I didn't get any pink frames. I can get 40-41 pictures (a little less than 2 seconds).
DNG are 1736 x 1156 pixels. Stunning quality compared to H.264...
But a little of moire (as usual with the 7D).
Congratulations to Magic Lantern !!! It's totally amazing what they can do.
